1. A process for converting carbon dioxide, the process comprising:
reacting, in a first reaction zone having a reactor and a regeneration vessel, operated under suitable conditions, carbon dioxide with coke to produce carbon monoxide;
circulating a heat supply media between the reactor and the regeneration vessel;
generating in an electrolysis zone operated under suitable conditions hydrogen from water, and,
reacting, in a second reaction zone operated under suitable conditions, the carbon monoxide from the first reaction zone with the hydrogen from the electrolysis zone to produce methanol.
